East Java Regional Police Arrest Dwi Bagus Martono for Madiun Murders
A missing persons investigation in East Java concluded with the arrest of Dwi Bagus Martono for the murders of his common-law wife Dini Hardiyanti, 30, and her four-year-old son, Arshaka Ghafa El Faezya, in Madiun, reported on October 26, 2026. Police state the suspect killed the victims at the Hotel Mataram Baru before burning their remains and attempting to destroy the bodies with a meat grinder.
How the Missing Persons Report Masked the Crime
The investigation began after family members filed a missing persons report at the Madiun Kota Police SPKT on October 5, 2026, stating the victims had been missing since September 20, 2026. According to Kasubdit III Jatanras Ditreskrimum Polda Jatim AKBP Arbaridi Jumhur, the suspect actively accompanied the victim’s family from Bogor to the Madiun Kota Police station to file the report, successfully maintaining the illusion that the mother and child were missing.
Investigators eventually uncovered discrepancies during the inquiry. Closed-circuit television footage from Hotel Mataram Baru on Jalan Dr. Soetomo placed the victims inside the establishment alongside the suspect. East Java Regional Police Director of General Criminal Investigation Komisaris Besar Polisi Roy Hutton Marulamrata Sihombing stated that officers arrested the suspect on the night of October 25, 2026.
Forensic Investigation and Disposal Methods
Following the arrests, police traced the movement of the bodies from the hotel room to a residential yard in the Winongo neighborhood. Investigators found that the suspect burned the corpses twice and utilized a meat grinder to break down body parts in an effort to destroy evidence. The suspect also considered discarding the remaining biological material into open waters.
Forensic teams recovered bone fragments from the suspect’s property to build the case. The investigation relies on physical evidence gathered from the scene to substantiate the sequence of events established by the East Java Police.
Family Demands Maximum Penalties and Retribution
Relatives in Bogor received news of the deaths through a younger family member, Mia, who had pressed authorities for answers. Dini’s 42-year-old elder sister, Rika, expressed profound grief and anger over the killings during an interview at her home in Puncak, Bogor, on October 26, 2026.
A life must be paid for with another life, especially since there are two. Yes, if not, just sentence them to death, or mutilate them.said Rika, detailing the family’s demand for the suspect to be punished as severely as possible.
Domestic Conflict as the Underlying Motive
Police point to domestic disputes as the catalyst for the killings. According to Roy Hutton Marulamrata Sihombing, the suspect held a deep grudge stemming from household tensions that escalated following communications between the suspect’s legal wife and Dini Hardiyanti.
Investigators continue to process evidence and examine the precise timeline of the domestic feud. The case parallels prior mutilation investigations in East Java, such as the 2025 Kediri murder prosecution handled by the Kediri District Court.
